Memory can be a tricky thing. For some, the ability to recall in perfect detail is useful. Certain professions can benefit, such as journalism, medicine, or sports. Those in law enforcement understand the brain is often influenced to such a degree that whatever sticks is sketchy. Take, for example, eyewitnesses at a crime. Ask ten people who see a bank robbery in progress what the gunman looks like and ten different answers will emerge. Uh-oh! The key is seeing how many times certain details repeat. More than say, five, and the sameness should be noted as likely accurate.
Memories of the past are the latest issue to deal with for everyone. Mostly, these are romantic in nature. One is a whopper, however. Add in a military weapon and the memories get even more twisted.
For the folks of Eureka, four get involved in the same event. They all travel back to 1947, and return. However, one snafu rises when Dr. Trevor Grant (James Callis) decides to come along ("A New World"). The little changes in town are nothing compared to what Grant has to offer. By merely being around, evidence starts to creep in and those in the alternate timeline are given hints of the large secret hidden not quite so well.
Grace Monroe (Tembi Locke), married to Henry (Joe Morton), finds out the truth when he blurts it up in an unguarded moment ("Momstrosity"). She's married all right, but to another Henry entirely. They are trying to start over as a couple to see if this Henry whom Grace doesn't know can win her heart.
Zoe (Jordan Hinson), daughter of Jack (Colin Ferguson), senses something amiss. Jack hasn't said anything, but he might in time. Jo (Erica Cerra), on the other hand, has Zane (Niall Matter) already suspecting trouble, but he guesses even more when he spots Jo wearing his grandmother's ring. Jo needs to tell him everything. I get the impression he could take it. The part about him proposing to her right before she left for 1947 ("Founders Day") might come as a shock, though. Could this mean he leaves her for Zoe as a form of retaliation? Stay tuned...
